A convergent algorithm for a generalized multivariate isotonic regression problem

Hansohm, Juergen; Hu, Xiaomi (Springer, 2012-02)

Sasabuchi et al. (Biometrika 70(2):465-472, 1983) introduces a multivariate version of the well-known univariate isotonic regression which plays a key role in the field of statistical inference under order restrictions. ...
On the convergence of row-modification algorithm for matrix projections

Hu, Xiaomi; Hansohm, Juergen; Hoffmann, Linda; Zohner, Ye Emma (Elsevier, 2012-02)

This paper proposes an algorithm for matrix minimum-distance projection, with respect to a metric induced from an inner product that is the sum of inner products of column vectors, onto the collection of all matrices with ...
